It's definitely useful and a big win. It both clears up general disk 
I/O, but more importantly (from what I have seen), moves certain key 
inodes in the delivery file structure off of disk, and since I/O 
operations have to lock and unlock them for update, the time wasted 
single-threading through them goes way down (this is why, for instance, 
you should generate a fairly large number of sub-queues in sendmail; if 
you're trying to do volume and haven't, you're being silly; it spreads 
the load across more than one inode)
